Stocks tumbled on US concerns and lower oil prices

LONDON — Shockwaves from President Donald Trump's failure to overhaul the Affordable Care Act, also known as Obamacare, hit the markets on Monday.

Investors were concerned that President Trump won't be able to cut taxes and increase spending to inflate the US economy as a result of the healthcare debacle, weakening the dollar and reducing prospects for global economic growth.

The UK's FTSE traded 0.85% lower as of 8:24 a.m. UK time (3:24 a.m. EST), while Germany's DAX fell 0.83% and the Euro Stoxx 50, a benchmark of leading European companies, was down 0.73% to 3,418.

"The FTSE is hindered by GBP strength (due to USD weakness) weighing on its 70% of internationally-generated profits as well as a drop in commodity prices (base metals Oil) as fresh risk aversion kicks in; a double whammy blow for Miners and Oil majors," Michael van Dulken, head of research at Accendo Markets, said in an email.

Oil took a knock on concerns the US is ramping up production.

"Crude Oil is starting the week on the back foot as the Baker Hughes Rig Count on Friday recorded its 10th weekly increase, adding to concerns that rising US production will offset OPEC's production cuts, given further impetus as rumours of an extension to the group's cuts and a weaker US dollar are failing to buoy prices," van Dulken said.
